Lego Minifigures Online, the new MMO from Funcom (The Secret World), has now gone into open beta. The final version of the game is set to go online this autumn, but in the meantime the studio will be expanding the title (there's currently three worlds - Pirate World, Medieval World and Space World - with more planned) as they seek to build a community. The PC version of the game is already up and running (you can sign up here), and a tablet version is in the works.
